长试样法测液体介电常数

Testing the Dielectric Constant of Liquid by Taking a Long Sample

摘要

摘要: 探讨了利用长试样法测液体介电常数时，对试样长度的限定以及液面位置的变化对测量结果的影响。给出了试样长度的最低限度，并通过实验表明：测量驻波比随试样长度呈一种周期性变化，其变化周期及极值点位置均与样品性质无关。

Abstract: The sample length-limit and the effect of place of the liquid surface are discussed.The inferior limit of the sample length is given .The experiment shows that the standing-wave radio change periodically with the change of the sample length
